When MR script finishes, I get both banner and regular notification

I run my backups from MR XML files and they run beautifully with one click. When they finish, they show a banner and a regular (in the notification centre) notification to the effect that the image and verification finished successfully in <time>.

I was just wondering whether there's a setting I can't find that makes MR show me one or the other, preferably the regular notification, since that sticks until I read it, while the banner is short-lived.
